Lili Reinhart "Smooches" 'Riverdale' Co-Star Camila Mendes

Lili Reinhart, 26, is known for her starring role as Betty Cooper in the CW show "Riverdale."

Many of the actors and actresses are not just close on-screen, but also off-screen having worked together since 2017. Lili Reinhart, for example, is very close with co-stars Camila Mendes and Madelaine Petsch (the three even plan Halloween costumes together every year.)

More recently, Reinhart shared photos of herself and "Riverdale" co-star Camila Mendes promoting Armani Beauty.

In a new Instagram post, the 26-year-old actress shared some photos of her and Camila Mendes, who portrays Veronica Lodge on "Riverdale." The two actresses wore matching black outfits as they promoted Armani Beauty.

Reinhart wore a black dress with a black blazer over her right shoulder while Mendes wore a black sleeveless top and an oversize blue velvet jacket.

Both wore dark makeup that highlighted their facial features and helped bring the entire look together.

"Smooch," Reinhart captioned the post.

A second photo shows Reinhart giving her "Riverdale" co-star a kiss on the cheek.

"Beauties! ?," "Riverdale" co-star Erinn Westbrook commented on Reinhart's post while "Euphoria" actress Sydney Sweeney commented, "Ok hotties ?."

A third Instagram user chimed in with, "i love you so much girls."

The popular CW show is coming to an end after seven seasons, which is bittersweet for the 26-year-old actress.

"It does. It has a bittersweet feeling to it," Lili Reinhart said. "And I think I'm kind of just trying to approach this season with not taking anything for granted, really trying to be present, trying to enjoy my co-stars. So, it's different for me at least."

Reinhart is close to her co-stars, especially Madelaine Petsch and Camila Mendes, who always post TikTok videos together. When speaking to her connection with the girls, Reinhart said, "We're all going to be going in such different directions, location wise, that I hope that when we do hangout and come together, we can find a way to make a TikTok."

Camila Mendes also spoke out about the beloved show ending, saying, “Everyone’s always like, yeah, ‘Free the Riverdale actors’ or whatever, but I think ultimately, we’re all going to be sad when it’s over."

"Any sort of creative artist seeks new challenges, and there’s a point in time when something ceases to be challenging. I think everyone’s just ready for that next chapter. It’s like we’re outgrowing the show in a way,” Mendes continued.

"Riverdale" has been airing on CW since 2017. The show is based on the Archie Comics series and stars KJ Apa

as Archie Andrews, Lili Reinhart as Betty Cooper, Cole Sprouse as Jughead Jones, Camila Mendes as Veronica Lodge, Madelaine Petsch as Cheryl Blossom, Vanessa Morgan as Toni Topaz, Casey Cott as Kevin Keller, and Ashleigh Murray as Josie McCoy.

The seventh and final season of "Riverdale" is expected to air in 2023 on CW. Seasons one through six are currently streaming on Netflix.
